German Defense Minister Karl Theodor zu Guttenberg says Army Inspector General Wolfgang Schneiderhan failed to provide adequate information about the incident in which civilians were killed.

Germany's top army officer has resigned over an investigation into a September air strike in Afghanistan in which civilians were among those killed.

German Defense Minister Karl Theodor zu Guttenberg announced Thursday that General Wolfgang Schneiderhan had resigned. Guttenberg told parliament that Schneiderhan failed to provide adequate information about the incident.

An Afghan government-appointed commission said 30 civilians were killed in the September 4 air strike in northern Kunduz province. A commission investigator says 69 Taliban members were also killed after a German commander ordered the NATO strike on militants who had seized two fuel trucks. Initial NATO investigations indicated that civilians were among the victims.
